I would assume that with physics, unlike psychology, or anything that involves biology, is that it's generally much easier to eliminate variables. Testing a new drug, for instance, is very difficult because there are about a billion chemical processes going on in the human body (or whatever body is being tested), and trying to distill the effects of adding one more, and making sure that the effects are correctly attributable to the right causes is something we can almost certainly never know 100%. This kind of thing certainly happens in physics, and we can see results like neutrinos appearing to travel faster than light until they are corrected, but it's usually much easier to isolate the processes of interest in a physics experiment than in a biological system, or at least easier to eliminate most extraneous effects.
